Current Time of Timezone

Question

I have different timezones and their GMT and DST. Example:

TimeZoneId        |   GMT offset  |   DST offset  
              


        

Answer 1

private static ReadOnlyCollection _timeZones = TimeZoneInfo.GetSystemTimeZones();

public static DateTime ToUsersTime(this DateTime utcDate, int timeZoneId)
{
    return TimeZoneInfo.ConvertTimeFromUtc(utcDate, timeZones[timeZoneId]);
}

An example of converting a UTC date to a user's date using the TimeZoneInfo class (.NET 3.5+).
